Asphalt Seal-Coat Treatments

Asphalt emulsions use surface-active agents or surfactants to suspend the asphalt particles in water These surfactants or emulsifying agents are similar to soap, allowing the minute asphalt particles and the water to form a uniform mixture When the asphalt emulsion is applied to the roadway, the asphalt cement and the water separate.

What is a Tack Coat?

The proper amount of tack coat emulsion must be applied, because if too little is used, the bonding between the two layers of asphalt will be too weak, and if too much emulsion is used it will affect the quality of the hot mix asphalt The application rate is very important Thus, if the surface is absorbent, then more tack coat is needed.

Oil emulsions

The common colors of emulsions are dark reddish brown, gray, or blackish brown; however, any color can occur depending on the type of oil and water at a particular facility Emulsion brightness is sometimes used to characterize an emulsion An emulsion generally looks murky and opaque because of light scattering at the oil/water interface.

Emulsified Asphalt

Emulsified asphalt is simply a suspension of small asphalt cement globules in water, which is assisted by an emulsifying agent (such as soap) The emulsifying agent assists by imparting an electrical charge to the surface of the asphalt cement globules so that they do not coalesce (Roberts et al, 1996 [1])Emulsions are used because they effectively reduce asphalt viscosity for lower.

Asphalt concrete

Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, as well as the core of embankment dams It consists of mineral aggregate bound together with asphalt, laid in layers, and compacted.

The Advantages of Asphalt Emulsions for Road Construction

Among other advantages of asphalt emulsion are: the viscosity of asphalt emulsion at room temperature is significantly lower than that of asphalt This allows emulsion to permeate even small pores and cracks; bitumen emulsion is highly adhesive to various surfaces, including metals, as well as acidic or basic minerals.
